Research Project: Development of Analytical Methods for Trace Elements and Elemental Species in Foods

Location: Food Composition and Methods Development Lab

Project Number: 1235-52000-046-00
Project Type: Appropriated

Start Date: Feb 22, 2004
End Date: Feb 21, 2009

Objective:
1) Develop robust multi-element methods and quality control materials for trace and ultratrace elements important to human health, 2) develop method for total vitamin B12 in foods, 3) develop elemental speciation methods for vitamin B12 (cobalamin), 4) develop analytical methods for the determination of hemeprotein and heme Fe in meats, and 5) develop elemental fingerprinting method for food and botanical materials.

Approach:
Analytical methods for the trace and ultratrace elements will be based on graphite furnace atomic-absorption spectrometry (GF-AAS), inductively coupled plasma-atomic emission spectrometry (ICP-AES) and ICP-mass spectrometry (ICP-MS). Total vitamin B12 and heme Fe will be determined using selective extraction and ICP-AES. Speciation of vitamin B12 will be based on capillary electrophoresis ICP-MS. Elemental fingerprinting methods will use semi-quantitative ICP-MS.
